摘　　要：目的明确河北产区桃中农药残留水平和风险状况。方法在河北省采集70份桃样品进行农药残留检测与分析,对检出农药残留进行急性和慢性膳食摄入风险评估,并利用风险排序矩阵对农药残留风险大小进行排序。结果 70批次桃样品共检出农药残留33种,农药残留检出率为100%,个别样品存在农药残留超标现象,超标农药为多菌灵和甲氨基阿维菌素苯甲酸盐。桃中检出农药的慢性膳食摄入风险(用%ADI表示,acceptable daily intake,ADI)在0.00%~1.06%之间,急性膳食摄入风险(用%ARf D表示,acute reference dose,ARf D)在0.00%~11.33%之间。根据农药残留风险排序结果,高风险农药共有5种,其中毒死蜱和甲氨基阿维菌素苯甲酸盐检出率较高,分别为45.7%和18.6%。结论河北地区桃样品中农药残留检出率较高,但94.3%样品的农药残留值符合国家限量标准,桃中农药残留急性和慢性膳食摄入风险均处于较低水平,其中,多菌灵、毒死蜱和甲氨基阿维菌素苯甲酸盐是桃中应重点关注的风险因子。Objective To determine thepesticide residue and risk level in peach from Hebei. Methods Totally 70 peach samples collected from Hebei province were detected. For the pesticides detected in the samples, acute and chronic dietary intake risks were assessed and the pesticide risks were ranked by the matrix ranking. Results It was showed that 100% of the peach samples had detectable residues and 33 kinds of pesticide residues were detected. Some pesticide residues in samples were over standard, such as polymycorrine and methylamabamectin benzoate. For the pesticides with detectable residues, the chronic dietary intake risks expressed as%ADI(acceptable daily intake, ADI) were 0.00%-1.06%, and the acute dietary intake risks expressed as%ARfD(acute reference dose, ARfD) were 0.00%-11.33%. According to the risk score, there were 5 high risk pesticides, among which chlorpyrifos(45.7%) and methylamabamectin benzoate(18.6%) had higher detection rates. Conclusion The detection rates of pesticide residues in peach samples from Hebei are relatively high, while 94.3% of the samples are under maximum residue limits(MRLs). Both chronic and acute dietary intake risks of pesticide residues in peach samples are very low. Among them, carbendazil, chlorpyrifos and methylamabamectin benzoate are the risk factors that should be paid attention to in peach.
